The same or similar components maybe designated by the same or similar reference numerals although theyare illustrated in different drawings. Detailed descriptions ofconstructions or processes known in the art may be omitted to avoidobscuring the subject matter of the present disclosure.

As described herein, the expressions “have”, “may have”, “include”,“comprise”, “may include”, and “may comprise” indicate the existence ofcorresponding features (e.g., elements such as numeric values,functions, operations, or components) but do not exclude presence ofadditional features.

As described herein, the expressions “A or B”, “at least one of A andB”, “one or more of A and B”, and the like may include any and allcombinations of one or more of the associated listed items. For example,the term “A or B”, “at least one of A and. B”, or “one or more of A andB” may refer to the case where at least one A is included, the casewhere at least one B is included, or the case where both of at least oneA and at least one B are included.

Terms, such as “first”, “second”, and the like, as used herein, mayrefer to various elements of various embodiments of the presentdisclosure, but do not limit the elements. For example, such terms donot limit the order and/or priority of the elements. Furthermore, suchterms may be used to distinguish one element from another element. Forexample, without departing the scope of the present disclosure, a firstelement may be referred to as a second element, and similarly, a secondelement may be referred to as a first element.

When an element (e.g., a first element) is referred to as being“(operatively or communicatively) coupled with/to” or “connected to”another element (e.g., a second element), it can be directly coupledwith/to or connected to the other element or an intervening element(e.g., a third element) may be present. In contrast, when an element(e.g., a first element) is referred to as being “directly coupledwith/to” or “directly connected to” another element (e.g., a secondelement), it should be understood that there is no intervening element(e.g., a third element).

According to the situation, the expression “configured to”, as usedherein, may be used interchangeably with, for example, the expression“suitable for”, “having the capacity to”, “designed to”, “adapted to”,“made to”, or “capable of”. The term “configured to” does not only mean“specifically designed to” in hardware. Instead, the expression “adevice configured to” may mean that the device is “capable of operating”together with another device or other components. For example, a“processor configured to perform A, B, and C” may mean a dedicatedprocessor (e.g., an embedded processor) for performing a correspondingoperation, or a generic-purpose processor (e.g., a central processingunit (CPU) or an application processor) that may perform correspondingoperations by executing one or more software programs stored in a memorydevice.

FIG. 1 is a block diagram illustrating an electronic device equippedwith a plurality of displays, according to an embodiment of the presentdisclosure. Referring to FIG. 1, an electronic device 100 includes twoor more displays (e.g., a first display 112 and a second display 114).

Each of the first display 112 and the second display 114 may be embodiedas, for example, a liquid crystal display (LCD), a light-emitting diode(LED) display, an organic LED (OLED) display, a microelectromechanicalsystems (MEMS) display, or an electronic paper display.

Each of the first display 112 and the second display 114 may display,for example, various contents (e.g., text, an image, a video, an icon, asymbol, and the like) through a display module 110,

However, the shape, the position, the size, and the type of each of thefirst display 112 and the second display 114 are not limited to thoseillustrated in FIG. 1. For example, a shape of each of the first display112 and the second display 114 may not be rectangular, or the sizes ofthe first display 112 and the second display 114 may be different fromeach other. Furthermore, the first display 112 may be disposed at thefront of the electronic device 100, and the second display 114 may bedisposed at the rear of the electronic device 100.

According to embodiments of the present disclosure, the first and seconddisplays 112 and 114 may correspond to independent display panels.Alternatively, the first and second displays 112 and 114 may correspondto different areas defined on a single display panel.

The electronic device 100 includes the display module 110, a processor120, a user input receiving module 130, and a memory 140. However, theelectronic device 100, as illustrated in FIG. 1, is only one of variousembodiments of the present disclosure and may be changed or modifiedbased on components illustrated in FIG. 1. For example, the electronicdevice 100 may further include input devices, such as, for example, akeyboard for receiving instructions or information from a user, a mouse,and the like. Furthermore, the electronic device 100 may further includean antenna, a radio frequency IC (RFIC), and a communication module forcommunication with an external device.

According to embodiments of the present disclosure, applicationexecution screens and the like may be displayed on the first display 112and the second display 114 under control of the display module 110. Theapplication execution screen may include the various pieces of content,as described above. Furthermore, the application execution screen mayrefer to a background screen including application icons, widgetscreens, and the like.

According to embodiments of the present disclosure, the processor 120may perform data processing or an operation associated with controland/or communication of at least one or more other components (e.g., thedisplay module 110, the user input receiving module 130, the memory 140,and the like).

The processor 120 may be implemented with, for example, a system on chip(SoC) and may include one or more of a CPU, a graphic processing unit(GPU), an image signal processor, an application processor (AP), or acommunication processor (CP).

The processor 120 may load and process an instruction or data, which isreceived from at least one other component, and may store a variety ofdata in the memory 140.

The processor 120 may apply available resources (e.g., hardwareresources, software resources, or the like) to the first display 112 andthe second display 114. In this case, the processor 120 may assignresources, which are available in common with respect to the firstdisplay 112 and the second display 114, to the first display 112 and thesecond display 114 as needed.

However, according to embodiments of the present disclosure, a resource(hereinafter a “first resource”) corresponding to the first display 112and a resource (hereinafter a “second resource”) corresponding to thesecond display 114 may have independently predetermined magnitudes(e.g., a first resource magnitude and a second resource magnitude). If ahardware resource or a software resource is used with respect to thefirst display 112, a resource may be assigned within a first resourcemagnitude range as needed. If a hardware resource or a software resourceis used with respect to the second display 114, a resource may beassigned within a second resource magnitude range as needed. Forexample, if the electronic device 101 has a RAM with a capacity of 8 MB,the processor 120 can assign up to 50% the RAM to the first display 112and can assign up to 25% of the RAM to the second display 114. In thiscase, if the hardware (i.e., RAM) resource is used with respect to thefirst display 112, the capacity of the RAM may be assigned within 4 MB(i.e., the first resource magnitude range) as needed.

For example, a resource may be assigned according to a request of anapplication executed by the processor 120. However, whether anapplication executed by the processor 120 is displayed on the firstdisplay 112 or the second display 114 may be determined in advance.

In an example in which the hardware resources are applied differently tothe first display 112 and the second display 114, the processor 120 maydetermine that hardware components accessible with respect to the firstdisplay 112 and hardware components accessible with respect to thesecond display 114 are different from each other. The hardwarecomponents may include, for example, a speaker, a microphone, areceiver, a sensor, a communication module, and the like.

In an example in which the software resources are applied different tothe first display 112 and the second display 114, the processor 120 maydetermine that a user account corresponding to the first display 112 anda user account corresponding to the second display 114 are differentfrom each other. Furthermore, the processor 120 may determine a securitylevel corresponding to the first display 112 and a security levelcorresponding to the second display 114 to be different from each other.

According to embodiments of the present disclosure, the user inputreceiving module 130 may receive a user input, which allows anapplication execution screen displayed on the first display 112 to bedisplayed on the second display 114. Alternatively, the user inputreceiving module 130 may receive a user input, which allows anapplication execution screen, displayed on the second display 114 to bedisplayed on the first display 112. The user input may be receivedthrough a menu user interface (UI) or may be received through anoperation of swiping a user's finger(s) on the first display 112 in adirection of the second display 114, or on the second display 114 in adirection of the first display 112.

The user input may include a touch input on the first display 112 or thesecond display 114 using a finger or stylus (e.g., an S-pen or thelike). The touch input may mean that the finger or stylus makes physicalcontact with a screen of the electronic device 100.

However, the user input may also be implemented when a finger or stylusdoes not make contact with a screen (e.g., a hovering state), Forexample, when a finger is within a. specified distance of the firstdisplay 112 or the second display 114, the electronic device 100 maydetect a variation in an electromagnetic field caused by the finger. Theuser input receiving module 130 may determine whether the user inputoccurs, based on the detected variation. Similarly, when the stylus isclose to the first display 112 or the second display 114, the user inputreceiving module 130 may determine that the touch input occurs,

According to embodiments of the present disclosure, the processor 120may allow an application execution screen, displayed on the firstdisplay 112, to be displayed on the second display 114 through thedisplay module 110, based on the user input received by the user inputreceiving module 130. Furthermore, the processor 120 may reset theapplication execution screen displayed on the second display 114 so asto use a hardware resource or software resource available with respectto the second display 114.

According to embodiments of the present disclosure, the memory 140 maystore data. The data stored in the memory 140 may include data exchangedbetween internal components of the electronic device 100, and dataexchanged between the electronic device 100 and components outside theelectronic device 100. For example, the memory 140 may store a list ofresources available with respect to the first display 112 and the seconddisplay 114.

The memory 140 may include an embedded (or internal) memory or anexternal memory. For example, the embedded memory may include at leastone of a volatile memory (e.g., a dynamic random access memory (DRAM), astatic RAM (SRAM), or a synchronous DRAM (SDRAM)), a nonvolatile memory(e.g., a one-time programmable read only memory (OTPROM), a programmableROM (PROM), an erasable and programmable ROM (EPROM), an electricallyerasable and programmable ROM (EEPROM), a mask ROM, a flash ROM, a NANDflash memory, or a NOR flash memory), a hard disk drive (HDD), or asolid state drive (SSD).

The external memory may include a flash drive, such as, for example,compact flash (CF), secure digital (SD), micro secure digital(Micro-SD), mini secure digital (Mini-SD), extreme digital (xD),multimedia card (MMC), or memory stick. The external memory may befunctionally and/or physically connected to the electronic device 100through various interfaces.

The display module 110, the processor 120, the user input receivingmodule 130, and the memory 140 may be implemented independently of eachother, or two or more of the components may be integrated.
